IMPROVED REFRIGERATOR.

The Schedule referred to in these Letters Patent and making part of the same.

drawing making part of this specification, and to the letters of reference lnarked thereon, like letters indi-l cating like parts wherever they occur.

To enable others skilled in the art to construct and ilse my in vention, I will proceed to describe it.

. My invention relates to a refrigerator for household use; and

It consist's in anovel manner of constructing and arranging the same, as hereinafter described,

In the drawing-' v Figure 1 is a vertical section through the center of my refrigerator, and v Figure 2 is a horizontal cross-section,of-the same, taken on the line a' a; of tig. 1. f f

In constructing. my refrigeratoizl firstprovide a cylindrical case tir-hotly, A., made'of sheet metal with donble'concentric walls, leaving an'air-space'of about V-an inch between the twovwalls, as shown in tigs..1

and 2.

The lower end of the body l provide with a hollow double bottom, and mount it upon short fee-t or legs, t', to'insulate it from the Hoor, as shown in tig. 1.

1n the upper end of the 'body I susperu'l an icebasket, I3, of near-ly equal diameter with the body, and havi1'|g in its bottom a small hole, d, and near its upper edge a series of openings, c, communicating with the surrounding chamber. I

Under the ice-basket B.,I suspend a water-pan, C, to receive the water resultant from the melting of the ice in the basket.

Io the water-pall I connect a slnall pipe, e, passing through the walls offthe body and discharging on the outside, as shown in tig. 1.

The ice-basket I also provide with a cover, D, which is removed to allow the introduction of ice, but which, when in position, completely closes the upper end of the body A, as shown in tig. l.

Through the inner wall, near the bottom of the chamber, I make a small opening,'a, and through the outer wall, near the top, I make openings, b, as clearly shown in iig. l.

Inside of the chamber I place circular skeleton shelves, F, supported at their outer edges byl rollers, f, which are secured tothe wall, as shown in figs. 1 and 2.

Through one side of the body A, I make an opening nd provide it with av hinged door, F, through which access is had to the chamber, this door being clearly shown in tig. 2.

The articles to be refrigerated are introduced through the door F, and are placed either upon the shelves E or upon the bottom of the chamber.

The shelves E may be turned around freely on the rollersf, so. as to bring any point opposite the door F, thus venabling `articles to be removed from the back of theshelves without disturbingoi" removing those.. in front. l

"lherairin theluppe'rpart of the chamber becoming `Icooledbygthe ice, descends to the lower portionai-id,` Apasses Aout through the openings a into .the air'fspaee `o bet-'weeif` the walls, and, as it becomes heated, as-

` cends, 'and passes ont through the openings b, as shown p bythe arrows on'the drawing. In this manner a constant circulation of fresh air is maintained.tln'oughout the refrigerator, serving to keep the contents cool and sweet. A A

The shelves E lmay be made of cast metal, as'shown, or of wire orwood, always making them open, to peruiit the free circulation of air.

rlhe water from pipe e may be allowed to run off as waste, or a cock may be applied to the outerv end of the pipe, and thewatcr retained for drinking purposes. \V|1en the water is to be used for drilciug, a lilter may beintroducedn anysuitablo manner between the icebasket and the water-pau. I

By suljiporting the shelves upon rollers in the manner described, dishes or articles 'of their full siae can be placed on them, which cannot be done where the shelves are mounted on a central shaft.

n The top and bottom I make of cast-iron, enameled, to prevent rusting.

The inside walls. when made of zinc, I coat with a preparation of shellac, winch prevents the oxidation of the zinc, or the accumulation thereon of any sediment, which would otherwise tend to render the air foul and taint the articles contained in the refrigerator.

It' preferred, the body may be made of sheet-iron, enameled all over, which prevents rust.

Having thus described my invention,

'What I claim is- 1. A refrigerator, consisting of the circular body with the hollow walls7 and t-he openings a, and b, with the ice-basket B and cover D, all constructed and arranged to operate substantially as described.

2. rllhe circular shelves, mounted on rollers j, attached to the inside wall of the refrigerator, so that each shelf can be turned independent of the others.
